JOHN M. BLADE, OF ALPHA, ILLINOIS.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 288,764, dated November 20, 1883.

- Application filed January 22, 1883. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. BLADE, a citizen of the United States, residing at Alpha, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of cultivators known as parallel or tongueless cultivators; and the invention consists in constructions and combinations relating to the joint or coupling which connects the plowbeams to the axle or beam-yoke, and to the connection of the runners to said yoke, all as hereinafter fully described.

In the accompanying drawings, which illustrate my invention, Figure 1 is a rear elevation of the beam-yoke and its supporting-runners, and a sectional elevation of the joint. Fig. 2 is a perspective of part of the joint. Fig. 3 is a side elevation of the cultivator. Fig. 4 is a sectional elevation of the joint and part of the plow-beam.

Referring to the drawings by letters, the same letter indicating the same part in the differentfigures, A represents the beam-yoke or axle. To each end of the yoke A a rectangular frame, B, is fixed.

G O are rectangular frames, one to each frame B, exterior and transverse to said frames B, and journaled thereto by a bolt, b, so that the frames 0 may oscillate on the bolt 1) as an axis.

D is a runner bolted to the front side of the frame 0 by bolts and curved downward and rearward, as shown at Fig. 3.

D is a brace secured by bolts (1 to the rear side of the frame 0, and extends downward, and is connected at its lower end to the runner D.

E is the draft-hook, which is simply a prolongation of one of the bolts (2.

The foregoing manner of connecting the runner with the beam-yoke, while it permits of all the movements common in this class of cultivator, at the same time forms a cheap, strong, and effective connection between these parts where there is great strain.

The plow-beams F are of any ordinary construction, and have ordinary handles, f, and ploughs f.

G G are blocks or plates, which receive the vertical end of the yoke A in grooves a, be= tween them. The block G has a journal, 9, projecting from its outer side. A block, H, with a semicircular groove in its front side, rests against the rear side of the journal 9, and has a stud, h, in its rear side, which projects into the forward end of the plow-beam. (See Fig. 4.) A strap, h, bolted to the plow-beam,

embraces the block H and extends around the journal g. when the plow is raised at its rear end the stud h will hold the block H to the plow-beam and rotate said block on the journal g.

I is a washer or cap, somewhat larger in di= ameter than the journal 9, and is held to the .end of said journal by a stirrup, J, which stirrup passes around the block G in a groove therein, and thence its ends pass outward through the block G and journal g, and have their outer ends threaded and provided with nuts 3', by means of which the blocks G G are held together, and the washer I held in place on the journal g, for'the purpose of retaining the strap h and block H in place on said j ournal. The nuts j are locked by a plate, K, which rests between them. The plate K is held in place by a staple, k. through which it passes at its upper end, and a bent catch, is, on which it rests at its lower end. As shown, the journal 9 is not in the vertical center of the plate G; hence, by turning the plates G G, the depth of plowing may be regulatedthat is to say, if the device shown in Fig. 2 were inverted, the plow would be raised from the I ground to a height equal to the distance of the axis of the journal 9 from the vertical center.

The distance between the plow-beams may be adjusted by turning the blocks G G around on the'yoke A, as is shown by dotted lines at Fig. 1.

The plow-beams may swing vertically on the journals g, and horizontally by the blocks G G, turning on the yoke A.

Having thus described my invention, what 3. In combination with the beam-yoke, plow- I 5 I claim as new, and desire to secure by Letters gangs, blocks G G, journal 9, washer I, and Patent, is stirrup J, with nuts j, the plate K, secured 1. In a cultivator, in combination with the by staple 7c and catch in, substantially as and 5 plow-gangs, and the beam-yoke A, and frame for the purpose specified.

O, constructed as described, and secured to the In testimony whereof I affix my signature in 20 frame 13 by a pivot-bolt, b, the runners 1), sepresence of two witnesses. cured to the frame 0, as described, and braced,

substantially as and for the purpose specified. JOHN M. BLADE.
